Remove it.

 DECstations seem virtually indestructible, so it's mostly the matter of 
how long people want to keep them.  The only serious issue is by now they 
have started to suffer from dead lithium batteries that have been moulded 
in their DS1287A RTC chips.  With Maxim taking Dallas over and then 
breaking their promise to produce replacements indefinitely this has 
become a real problem now (I did not dare trying any of the imitatations 
the Chinese seem to offer these days).  A hack exists to rework old 
DS1287A (and similar) chips with a saw, a soldering iron and some skill 
for an external battery, but it requires some extra space around the chip 
and there is little in the DECstation because the DS1287A has been placed 
in the TURBOchannel option card area with little clearance left between 
the IC and any option card installed.

 As to the PMAG-AA board itself -- well, this is indeed a very rare item, 
but I happen to have a specimen.  To support it properly I'll first have 
to wire it to a monitor somehow though; signalling is standard, 1.0 Vpp 
composite monochrome, but what looks to me like a type F connector is used 
for video output, quite unusually for a graphics card (and for DEC itself 
too as 3W3 was their usual video socket).  It looks to me like converting 
it to BNC and then a standard DE-15 VGA connector (via the green line) 
will be the easiest way to get image produced by the adapter on a 
contemporary monitor (sync-on-green required of course, but with LCD 
devices being the norm now that seems less of a problem these days).

 Thanks, but the changes required are actually much more than that -- the 
driver has never been converted to the modern TURBOchannel API.  I have 
now dug out an old patch I was working on back in 2006 to convert this 
driver as well as drivers/video/maxinefb.c.  I'll try to complete the two 
drivers as soon as possible (unfortunately I can't test the latter at all; 
it's for an onboard graphics adapter of another DECstation model), 
although I now remember the main reason I didn't complete them back then 
was they used an old internal API that was removed and no suitable 
replacement provided.  I need to investigate again what that actually was 
though (hw cursor probably).

pmag-aa-fb.c still has struct display_switch (for the old drawing API) and the
old fb_ops (with get_var()/get_fix()), instead of the new fb_ops (rectangular
drawing API and var/fix as member data).

 That I got covered already in the old patch, but there was something 
else.  Otherwise I would have pushed it along updates for pmag-ba-fb.c and 
pmagb-b-fb.c long ago.

Joe,

 Just a quick update.

 So more weirdly even that's actually a TNC connector rather than a type F 
one.  I've got a suitable TNC->BNC adapter now (although regrettably such 
adapters seem to be available as 50Ù parts only; hopefully any distortion 
won't be too significant or maybe my digital monitor will even be able to 
compensate it, but at £1.76 (~$2.64) per item it's certainly worth trying 
before resorting to the original DEC TNC->BNC cable still apparently 
available from second-hand part suppliers at ~£80/$120 per a mere 1ft 
part) and a BNC->DE-15 cable is on the way.

 So I think I've got all the basic stuff covered now, including a change 
similar to your proposal as well as a conversion to the driver model/new 
TURBOchannel support infrastructure.  But what I remembered is actually 
right, the issue is wiring hardware cursor support into fbcon.  The driver 
uses its own display_switch structure with its own aafbcon_cursor handler 
to use the twin onboard Bt431 chips for cursor generation (there's also 
aafbcon_set_font that pokes at the Bt431s for cursor dimension changes).  
I need to figure out what the best way will be to make the fbcon subsystem 
support such an arrangement and that'll take me a little bit yet, so 
please be patient.

 Note that the board is weird enough to have a 1-bit (true monochrome) 
graphics plane, however the Bt455 used by the MX graphics adapter for 
screen image generation is a 4-bit grey-scale video RAMDAC (only the LSB

Joe,

 Just a quick update.

 So more weirdly even that's actually a TNC connector rather than a type F 
one.  I've got a suitable TNC->BNC adapter now (although regrettably such 
adapters seem to be available as 50Ω parts only; hopefully any distortion 
won't be too significant or maybe my digital monitor will even be able to 
compensate it, but at £1.76 (~$2.64) per item it's certainly worth trying 
before resorting to the original DEC TNC->BNC cable still apparently 
available from second-hand part suppliers at ~£80/$120 per a mere 1ft 
part) and a BNC->DE-15 cable is on the way.

 So I think I've got all the basic stuff covered now, including a change 
similar to your proposal as well as a conversion to the driver model/new 
TURBOchannel support infrastructure.  But what I remembered is actually 
right, the issue is wiring hardware cursor support into fbcon.  The driver 
uses its own display_switch structure with its own aafbcon_cursor handler 
to use the twin onboard Bt431 chips for cursor generation (there's also 
aafbcon_set_font that pokes at the Bt431s for cursor dimension changes).  
I need to figure out what the best way will be to make the fbcon subsystem 
support such an arrangement and that'll take me a little bit yet, so 
please be patient.

 Note that the board is weird enough to have a 1-bit (true monochrome) 
graphics plane, however the Bt455 used by the MX graphics adapter for 
screen image generation is a 4-bit grey-scale video RAMDAC (only the LSB 
inputs of its pixel port are wired to the graphics plane) and the twin 
Bt431s use the overlay plane to produce a 2-bit grey-scale cursor.  So we 
do want to use the hardware cursor to be able to make it prominent among 
the characters displayed throughout the screen and a software-generated 
cursor cannot really substitute what hardware provides.

I hope you're enjoying tinkering with old toys.

Best of luck getting it going.

[PATCH 2/2] framebuffer: Fix int cast to pointer warnings

[Joe Perches]

Casts of int to pointer need additional casts to (unsigned long)
when compiled for x86-64 to silence the compiler.

What's the warning? I'm not seeing anything on my machine when compiling
these two.

I wondered if I should even change it

Maybe you should just leave it in.
